APPARATUS FOR REPAIRING ASPHALT PAVEMENTS.

SPECIFICATION forming part of Letters Patent No. 574,681, dated January 5, 1897.

'application tiled May 25, 1895. Serial No. 550,706. (No model.)

To all whom t may concern- Beit known that I, PHILIP W. HENRY. of the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Repairing Asphalt Pavements, of which the following is a specification, reference being had to the accompanying drawings.

The object of my invention is to produce a comparatively simple, economical, ande lfective apparatus for applying heat to the surface of pavements composed of asphalt or similar material in order to soften t-he material of a spot to be repaired in a manner well understood in the art.

In the accompanying drawings, Figure I is a side elevation of one form of embodiment of myiuvention. Fig. II is a plan view thereof. Fig. III is an end view of the same. Fig. IV is a plan view of a modified form of my heater. Fig. V is a section of the line 5 5 of Fig. IV. Fig.VI is an end view of the heater, looking toward the forward part. Fig. VII is a side elevation of another modification. Fig. VIII is a plan view thereof. Fig. IXis an end ele vation of the same.

Referring to the gures on the drawings, 1 indicates the bed, body, box, or fuel-basket of my apparatus. It may be constructed in any suitable manner, of any non-combustible material, preferably iron, and may be made in the form of acomparatively shallow oblong receptacle, as illustrated. Its distinctive fea- -ture is that it is provided with an open-work or perforated bottom. This may consist of the perforated or reticulated fabric 2, as shown in Figs. I, Il, and III of the drawings, or of ordinary grate-bars 3, lying upon cross stay-rods 4, as shown in the remaining figures of the drawings. It is immaterial what form of open-work is adopted, since the object is to permit the radiation from a mass of incandescent fuel in the basket through the bottom against a pavement.

The purpose of my invention being to produce a portable heater having a fuel-basket, which is vertically adjustable to and from a pavement, I provide wheels 5, which support the body or basket upon a suitable frame. The number of wheels is not material, nor is dle-bar 15.

the shape, size, and character of the frame essential. For example, in Figs. I to III, inclusive, of the drawings thel frame consists of an arch b', which may be made up of suitable pipe-sections and angles, and which is provided with axles 7 for carrying one pair ofv wheels. The body or basket, as illustrated in those figures, is supported by chains S, wrapping around an axle 9, supported in bearings 10 in the frame.

11 indicates a crank for operating the axle 9', by means of which the body may be raised and lowered, as required. Asasuitable, simple, and convenient'means of fixing the position of adjustment of the body, I provide a ratchet-wheel l2, liixed to the axle 9, and a pawl 13, pivoted, as indicated at 14, toa han- The handle-bars are two in n umber, and are united bya cross-piece 16 at the forward end,which affords a means for hauling the heater from place to place, and also affords means of support for the legs 17, whereby the frame 6 is prevented from tilting upon its axle '7. To hold the body level, I provide chains 18, secured to it at its forward end, and wrapping around an axle 19, carried in bearings 2O in the opposite handlebars. This axle is also provided with a crank 2l, a ratchet 22, and a pawl 23, pivoted, as indicated at 24, to one of the handle-bars. By this means the body may be kept suspended in the horizontal position to correspond with the degree of adjustment effected by the su pporting-chains S.

In Figs. IV to.VI the body part itself is incorporated into a supporting-frame and is provided with j ournal-brackets 25 at its rear end and a bracket 26 at its forward end. They are revolubl y secnred,respeotively,to squared eccentric axles 27 and 2S. On account of the eccentricity of the axles they may be adapted to sustain the body elevated, as indicated in full lines in the figures referred to, or lowered, as indicated in dotted lines therein'. For securing the axles in the fixed position the mechanism illustrated in Figs. IV to VI, iny ICO each beingI provided with a hook 3l, which fits the squared part of the axle and prevents its rotation.

IVith respect to the front axle the box 26 is provided with a vertical swivel-pin 32, Which is sustained in the upright position by a rec tangular frame 33.

Movably secured to the pin are two stirrups 34, which fit over the squared axle 2S and which, being` united by a cross-piece 35, prevent the rotation of the axle in the box 26, but when the stirrups are removed the axle may be readily adjusted to the required position. Draft-hooks 3G afford means for transporting the heater.

In Figs. VII to IX, inclusive, I have shown still another modification of the embodiment of my invention. The body is shown as carried between an inclosing frame 37. This form is supported by four Wheels 5, carried in suitable swivel caster-frames 3S, located approximately at the four corners of the frame Near its opposite end the frame 37 is provided with boxes 39, in each pair of which is journaled an axle 40, and each axle is provided With a ratchet 4l and a controllingpawl 42, pivoted to the frame 37. To the axles 40 are secured at one end chains 43, which are fastened at the other end, as indicated at if, tothe bottom of the fuel basket or body. By means of the axles LIO and the chains 4.3 the basket may be raised or lowered as required and the axles may be adjusted To required positions by means of the ratchet 4l and pawl 42.

From the foregoing specification and description of the various modifications of the form of embodiment of my invention contained therein it will appear that the details of the invention are susceptible of Wide variation.

IVhat I claim is- In a heating apparatus for softening asphalt pavements, the combination With a portable supporting-frame, of an open fuelbasket adapted to contain a bed of solid incandescent fuel, and having aperforated bottom through which the lower surface of the bed of fuel is exposed, and adjustable suspension devices which permit the fuel-basket to be lowered in close proximity to the surface of the pavement, or raised to clear the rid ges of the pavement in transporting the apparatus, substantially as set forth.

In testimony of all which I have hereunto subscribed my name.

PHILIP IV. HENRY.
